Atmospheric Radiation and Climatic Effect of Greenhouse Gases

将使用一系列数值模式来研究大气辐射、动力学和化学之间的相互作用，特别是关于大气微量气体增加的气候影响。这项为期三年的项目将利用平流层和对流层的二维模型来研究微量气体增加对全球和区域臭氧产生的影响，以及臭氧和其他具有辐射活性的微量气体的变化对对流层气候的综合影响。在初始辐射强迫方面，二氧化碳的增加与其他辐射活跃的痕量气体之间存在着显著的差异。将使用国家大气研究中心的社区气候模式进行大气环流模式模拟，以调查二氧化碳和其他微量气体增加在随后的气候反馈中造成的任何差异。该项目将增强我们对影响气候系统的重要物理和化学过程进行建模的能力，并可能有助于更好地理解其他大气痕量气体将在多大程度上加剧二氧化碳温室气体温室效应。

A hierarchy of numerical models will be used to investigate the interactions between radiation, dynamics and chemistry of the atmosphere, especially in regard to climatic effects of increases in atmospheric trace gases. The three year project will utilize 2-D models of the stratosphere and the troposphere to study effects of trace gas increases on global and regional ozone production, as well as the combined effects of changes in ozone and other radiatively active trace gases on the tropospheric climate. There are significant differences in initial radiative forcing between increases in CO2 versus other radiatively- active trace gases. General circulation model simulations using the Community Climate Model of the National Center for Atmospheric Research will be carried out to investigate any differences in subsequent climatic feedbacks caused by increased CO2 and other trace gases. This project should enhance our capability to model important physical and chemical processes that affect the climate system and may lead to improved understanding of the extent to which C02 greenhouse warming will be augmented by other atmospheric trace gases.
